Provide geospatial traffic information in a dynamic way

Photo by on

After having introduced the challenge of location referencing in its general form in a and detailed the case of , I will describe this time the more general and modern approach for providing geospatial traffic information. The mobility is by definition a fully dynamic system, so it is natural to think about a dynamic way for providing detailed and updated traffic information. Dynamic Location Referencing (DLR) schema are conceived to be map-agnostic, i.e. the sender of the traffic information and the receiver should not have the same digital…

When repeating multiplications with your child leads you to discover many interesting algorithms

Photo by on

Having an 8-year-old child it is natural to ask him what he is learning in school. As the new school year has just begun, the math teacher is repeating the four basic operations for the benefit of the whole class. So far so good until I see that there is a full page of multiplication in several digits, and immediately I wondered myself how I could save time by solving them as quickly as possible. this initiates the discovery of a compelling story about increasingly efficient algorithms…

The case of pre-coded locations and the need of radio broadcasting traffic information

Photo by on

In a prevoious I introduced different ways in which geospatial information can be shared between different persons. Now I will focus on the case where we use pre-coded locations. Let’s remind that we are dealing with a situation where the actor A wants to communicate an information related to his map to anoter actor B having a different map. The strategy we are going to describe is to share a common predefined set of locations that each actor can relate to his map. …

How the Hellenistic genius computed the area of the parabolic segment without Calculus

Who does not know who Archimedes is. There are many anecdotes on him ranging from the famous “Eureka!” to the burning mirrors. We are in 300 BC, perhaps the most intellectually prosperous historical period in Europe until the end of the Middle Ages thanks to the Hellenistic culture. Archimedes was the prince of Hellenistic science, an undisputed genius able to range in every field of knowledge. For this reason, maybe, many of his works in the following centuries were lost because they were not understood by posterity and therefore not transcribed.

I will describe an Archimedes’ result in geometry: how…

How to properly provide geospatial data

Photo by on

One of the first spatial concepts we learn when we are children is the relative position of an object, like above the table, under the bed, in front of me, behind my mom, next to the chair. During our life we refine these concepts by introducing the notion of cardinal points, the idea of a reference system and coordinates (first of all to play ), until we understand their practical usefulness in giving road information. Imagine you are in a city you never have been and you do not have any map, neither digital or paper. You are looking for…
